Description

The
herbaceous plant is
perennial. It can reach heights of up to 3 metres (9.8 ft). The leaves are oval, and grow to 7 centimetres (2.8 in) to 10 centimetres (3.9 in) wide, and 10 centimetres (3.9 in) to 25 centimetres (9.8 in) long. The plant has been imported to
Europe, and it is seen as an
invasive species - few
animals eat it, and it will take away the space of other plants. This means that often, there is uncontrolled growth.
